doctest failed about learn4haskell HOT 2 CLOSED

Ok, thank you!
I forgot about my .ghci settings. 😕

from learn4haskell.

Hi @juev! Our doctest tests don't expect the line it :: Num a => a and similar ones. By default, GHCi doesn't print the type of each expression. You probably enabled this option in GHCi somehow (either explicitly or implicitly from some GHCi config file) by running the :set +t command. When inserting answers to GHCi, you either need to insert everything before the it :: ... line, or execute the :unset +t command after entering GHCi to avoid seeing this line.

Hope this helps! Let us know if the problem still persists.
